Audison APX 6.5 Datasheet

Frequently Asked Questions about APX 6.5


What technical features define the APX 6.5 speaker?

The Audison APX 6.5 is a 6.5'' coaxial speaker with a concentric coaxial tweeter. This creates a precise soundstage with a uniform phase response through a single emission point. The 32-mm voice coil made of pure copper offers high power handling and excellent control of low frequencies. With a woofer frequency response of 60 ÷ 23k Hz and a 4 Ohm impedance, it impresses across all tones. The water-resistant paper cone, developed with KLIPPEL technology and optimized for OEM integration, ensures universal applicability, even with off-center placement. The compact basket with abrasion-resistant coating provides robustness.

How does the voice coil of the APX 6.5 affect audio performance?

The 32-mm voice coil of the APX 6.5 is made of pure copper, making it particularly powerful. This design allows for high power handling with a maximum input power of 210 watts and a continuous power of 70 watts. The excellent control of low frequencies is a direct result of this voice coil quality. In addition to the voice coil, Bluetooth and WiFi connectivity influence the setup's surrounding flexibility. The voice coil significantly contributes to the precision of the sound image by operating without distortion even at higher volumes, thus enabling an accurate representation of musical pieces.

What technology was used in the development of the APX 6.5?

The Audison APX 6.5 was developed with KLIPPEL technology, which optimizes acoustic performance, especially in OEM integration. This technology helps analyze and improve all critical parameters for sound reproduction. This includes the FEM simulation of the water-resistant paper cone, which allows for precise calculation of the resonance frequency of 80 Hz. With an Xmax of 2 mm, the speaker guarantees linear displacement in both low and high frequencies. The KLIPPEL technology ensures outstanding sound even with complex musical pieces.

How do woofers and tweeters differ in the APX 6.5?

In the APX 6.5, the woofer with a size of 165 mm and a frequency range of 60 ÷ 23k Hz defines the low frequencies, providing precise control through its sturdy construction and 32 mm voice coil. The tweeter, on the other hand, is more compact at 24 mm and specifically optimized for higher frequencies, which is reflected in a tweeter SPL of 94 dB. The concentric coaxial tweeter in the woofer ensures uniform radiation from a single point, maintaining stable phase alignment. Both components synergize for a coherent and high-quality sound experience.

What parameters improve the OEM integration of the APX 6.5?

The APX 6.5 was specifically designed for optimized OEM integration. A key feature is the low profile, made possible by the flat basket with its abrasion-resistant coating. Additionally, the speaker offers a quick and reliable connection through the high-current quick-connect terminal without complicated wiring, saving time and effort during installation. The 4-ohm woofer impedance ensures compatibility with most factory amplifiers. The various customization options guarantee perfect acoustics, even in challenging installation situations.

How is the soundstage of the APX 6.5 optimized?

The soundstage of the APX 6.5 is optimized by the concentric coaxial tweeter, which allows for uniform sound emission. This design minimizes phase issues, as both the low and high-frequency ranges are radiated from a single point. The acoustic lens ensures that the frequency response remains extremely linear even in off-axis placement. These features guarantee excellent sound projection by minimizing distortion and maximizing sonic precision. The "Triple-Wave" TPU suspension helps ensure stable displacement, providing consistent sound quality.

How does the water-repellent paper cone affect performance?

The water-repellent paper cone of the APX 6.5 stands for durability and stability, even under demanding conditions. Developed through FEM simulation, it withstands moisture that often occurs in vehicles due to temperature and humidity fluctuations. This protects the internal components from corrosion and guarantees consistently high sound quality. The special treatment of the cone, combined with the 32 mm voice coil, supports precise control of the bass range. Its robust design allows for constant performance, even under higher loads and prolonged use, making it optimal for mobile applications.

What advantage does the high-current quick-connect terminal offer?

The high-current quick-connect terminal of the APX 6.5 ensures a fast and secure installation. It reduces the risk of short circuits through the double contact area and the temperature-resistant plastic cover. For installation, this means not only less wiring effort but also increased safety. Another plus is the galvanic isolation, which ensures a stable power supply. Especially in audio installations in the automotive sector, where vibrations and mechanical stresses occur, this technology is particularly valuable for ensuring interference-free performance and a long lifespan.

Is the APX 6.5 compatible with my vehicle?

The APX 6.5 is suitable for a variety of vehicles due to its optimized installation depth and flexible connection options. Thanks to the flat, abrasion-resistant basket, the speaker can be used in limited space conditions. A 4-ohm woofer impedance ensures broad compatibility with many common amplifier models. Additionally, the installation depth has been deliberately tailored to the requirements of OEM installations, achieving an optimal fit in most factory installation locations. The adaptability of the design allows for seamless integration, even in compact automotive interiors.

What frequency ranges does the APX 6.5 cover?

The Audison APX 6.5 covers a frequency range from 60 Hz to 23 kHz, making it ideal for reproducing a wide sound spectrum in vehicles. The woofer is capable of producing powerful bass tones with a flexible Xmax of 2 mm, while the compact tweeter covers the clear highs. Thanks to the 32 mm voice coil and the optimized acoustic lens, the frequency response is kept linear, which is particularly advantageous in vehicles with fluctuating acoustic conditions. This wide frequency coverage enables precise and dynamic audio playback.
